Title:
Bright Star Regulus near the Leo 1 Dwarf Galaxy
Explanation:
The star on the upper left is so bright it is sometimes hard to notice the galaxy on the lower right. Both the star, Regulus [ http://en.wikipedia…], and the galaxy, Leo I [ http://en.wikipedia. org/wiki/Leo_I_(dwar f_galaxy) ], can be found within one degree of each other toward the constellation of Leo. Regulus [ http://www.astro.ui…] is part of a multiple star system [ http://homepage.uni…1158.htm ], with a close companion double star [ http://antwrp.gsfc.…] visible to the upper right of the young main sequence [ http://observe.arc.…] star. Leo I is a dwarf spheroidal galaxy [ http://www.astro.uu…] in the Local Group [ http://www.seds.org…] of galaxies dominated by our Milky Way Galaxy [ http://antwrp.gsfc.…] and M31 [ http://antwrp.gsfc.…]. Leo I is thought to be the most distant of the several known small satellite galaxies [ http://www.astro.uu…] orbiting our Milky Way Galaxy [ http://antwrp.gsfc.…]. Regulus is located about 75 light years [ http://starchild.gs…] away, in contrast to Leo 1 which is located about 800,000 light years away.
